During the relatively
short construction interval — which can last from six months to a year, depending on the size and scope of the project — the
wind turbines are touched more
than at any other time throughout the life of the project.
The authors simply dismissed actual reported field CFs as irrelevant and not valid because they allegedly apply only to
short, «low - power
turbines with small diameters in slow -
wind areas [less
than 7 to 7.5 m / s annual
winds]...» The authors, however, fail to explain why the higher power windmills with large diameter blades were not available before, if indeed this combination is
wind energyís economic panacea.
